Push Notifications not working, have never worked


I installed RC server using instructions here: https://rocket.chat/docs/installation/paas-deployments/aws/

So I’m running server version 0.74.2, and iOS client version 3.4.1 (250).

I’m using the standard RC client apps from the app stores, and I have the default push gateway https://gateway.rocket.chat configured.

When I click the send test notification button on the push admin settings, I receive a push notification. However no one ever receives push notification to their mobile device, iOS or Android.

What am I doing wrong? No one else seems to have or encountered the same issue.
